Baader CCD Complete Filterset 2inch
with LPFC: Baader CCD Complete Filterset 2inch with
LPFC is designed for CCD astrophotography and an essential accessory for lunar
and
planetary observations. The filters allows for recordings with the same exposure
time that
is considered very important for automated continuous shooting. Baader's LRGB
filters
deliver improved color separation and image quality without annoying halos. The
Baader
Blue filter passes virtually all of the H-Beta and O-III lines, while the Green
filter is
able to capture all of the O-III line without encroaching into the H-Beta line.
In
addition, the Green and Red filter passbands nearly touch, leaving only a sharp
notch to
block out the primary Mercury/Sodium light pollution line at 580nm. The high
transmission
everywhere else delivers the shortest combined exposures possible with every
detector. The
Baader O-III perfectly isolates the two doubly ionized oxygen lines through a
very sharp
and narrow bandpass, the narrowest of any O-III filter, while the Baader SII
will block
all unwanted sodium light pollution and longer wavelengths. Baader's H-Alpha
filters ultra
narrow bandwidth with extremely high transmission rates enables high-contrast
deep sky
images. The high optical quality of the Baader narrowband filters guarantees no
loss in
sharpness or contrast. Each substrate is fine-optically polished plane parallel
to deliver
a smooth and accurate 1/4 wavefront over the entire surface. This special custom
polishing
operation sets Baader filters apart from the standard commercially precision
polished
filter substrates used by most other filter manufacturers. Baader Planetarium
filters are
truly designed to be stacked and combined due to the high optical quality and
highly
efficient anti-reflection multi-coatings. Premium quality coating is applied
that offers
optimum light transmission.
